He didn’t explain what he had on Heidi Cruz, but the Texas senator was furious that his wife was being dragged into the heated presidential race.

Cruz insisted he had nothing to do with the Melania Trump ad, which was funded by anti-Trump super PAC Make America Awesome.

On Wednesday, Cruz blasted what he called Trump’s “gutter politics” during a press conference in Manhattan, describing it as part of a pattern.

“He tries to attack and bully. That is his pattern that he does over and over,” Cruz said.

He shrugged off the impact on his wife, a former Goldman Sachs investment banker, saying, “She is used to dealing with bullies, and Donald Trump doesn’t scare Heidi remotely.”

Cruz also called the ad “completely inappropriate.”

Heidi Cruz responded on her own, while campaigning for her husband in Wisconsin.

“Most of the things Donald Trump says have no basis in reality,” she said.

Trump wasn’t buying Cruz’s protestations, tweeting Wednesday, “Lyin’ Ted Cruz denied that he had anything to do with the G.Q. model photo post of Melania. That’s why we call him Lyin’ Ted.”

The meme-friendly ad that enraged Trump features an old photo of Melania, covered only by the fur she is lying on, with the words — “Meet Melania Trump. Your Next First Lady. Or, You Could Support Ted Cruz on Tuesday” — across the image.

The picture came from a British GQ magazine photo-shoot in 2000, when Trump and the then-Melania Knauss were dating. The couple married five years later.

Trump waded deeper into the schoolyard tussle on Wednesday night, retweeting an unflattering photo of Heidi next to a glamour shot of Melania.
